Here is the F-4B Phantom model made by DHK79, the model imports easily into RF-X and fly's great, the only mods I made was change steering gear to "springy scale retracts", (to stop the wheel sticking to the runway) leave main gear as is, increase H-stab and V-stab strengths, under the servos tab alter launch 1-2-3-4 to 1.0 each and release 1-2-3-4 to 0.5 each, play around with these numbers to get two missiles in flight.
While the video gives the impression of chasing missiles, what is actually happening is the missile launches and fly's a hundred feet in front of the F-4B, controlling the aircraft also controls the missile, just gives a fun visual effect.
